1982年Livaditis和Thompson报道将金属蚀刻技术用于铸造金属翼板固位体,研制成新型的无固位孔铸造金属翼板蚀刻粘结固定桥,使蚀刻铸造金属翼板同复合树脂的粘结力,超出酸蚀釉质同复合树脂粘结力的二至三倍。这种铸造金属翼板蚀刻粘结固定桥又称为Maryland桥。我们自1983年9月以来,采用这种技术并稍作改进为患者制
1982 Livaditis and Thompson reported that the metal etching technology used in casting metal wing retainer, developed a new type of non-retaining hole cast metal wing etching bonded fixed bridge, so that the etching of the metal foil bonding with the composite resin Force, beyond acid enamel bond with composite resin two to three times. This cast metal wing etching bonded fixed bridge, also known as the Maryland bridge. We have been using this technology since September 1983 and have made minor improvements to patients
